). I didn't have them changed and am looking into it myself. I first took the drivers side tire off and inspected. I immediately found that the bottom caliper bolt had completely backed off (loose and not engaged in the thread at all). I tightened this and all the other bolts (none of which were loose) and took it for a test drive. Vibrations still there. Next I took off the passengers side tire (which had been put on with extremely high torque i might add) and inspected for loose bolts. I found one of the caliper frame bolts a little loose but not seriously. Again I put the tire back on and took it for a drive and of course the vibration was still there. Next I went to MVS to look through threads and found many with different issues. My biggest question is how do I know what is causing the vibration. I know it could be warped rotors, but it also sound like it could be the rear delta link bushing. If it was the rear would I be able to recreate the vibrations using the E-brake? Would the rear rotors give me the same feeling as the front rotors? What would be the best course of action to take first?Extreme Braking Vibrations on my 2002 v70-xc
Extreme Braking Vibrations on my 2002 v70-xc
I replaced my front brake pads and rotors last summer. Over the last several months I have had an increasing braking vibration when ever I brake from 30MPH +. I took it to a garage and they told me it was my rotors and they were too wore to turn (but I had just changed them ). I didn't have them changed and am looking into it myself. I first took the drivers side tire off and inspected. I immediately found that the bottom caliper bolt had completely backed off (loose and not engaged in the thread at all). I tightened this and all the other bolts (none of which were loose) and took it for a test drive. Vibrations still there.

Not delta link as your car does not have the same suspension in rear.
Is the vibration a steering wheel shake or a vibration felt in whole car with no strong feedback in steering wheel?
Whole car is rear and steering wheel shake is front. As a guide anyway, not a wholly conclusive test.
If it is front then the loose bolts in brakes or the irregularly tightened wheel bolts may have created a wear pattern on the front rotors that will require that they be replaced or machined to true them again.
Many things can cause vibration while braking and a worn steering part can contribute to vibration.
